Abstract

The ubiquitous sensor-rich smartphones
have promoted Mobile Crowdsensing (MCS), an emerging
people-centric sensing paradigm for urban Internet-of-
Things (IoTs). However, using cellular networks to transmit
the big data collected by MCS would incur expensive
financial costs for both participating phone users and the
MCS organizer. A promising solution to this is to integrate
the low-cost Devices-to-Device (D2D) communication into
the MCS design. Yet using D2D in MCS will require the cooperative
interactions among the self-interest and strategic
participating phone users, which significantly complicates
the ”human-in-the-loop” MCS design in both digital and
human dimensions, and brings a branch of new challenges:
(1) data communication and networking become more
complex; (2) D2D connections among opportunistically
encountered phone users must be secure, fast, and user
transparent; and (3)participating phone users need to be
properly incentivized. In dealing with these challenges,
this article will cover recent developments of D2D-enabled
MCS from both theoretical and practical perspectives.
Future research questions in this rapidly growing field are
also discussed.
